srnaM-rnnssuanfsrnmnrznn VALVE.

Be it known that I, ALBERT M..AUFTR1NG, a citizen of the United States of America, and a resident of Hammond, county of Lake, State of Indiana, have invented certain new and useful Improvements in Steam-Pres-- sure-Sterilizer Valves, of which the Vfollow.-A

ing is a specification.

The mam ob]ects of this invention are to provide an improved form of valve' for use on sterilizing apparatus designed to insure and facilitateproper operation of theap-k paratus; -to provide an improvedarrange ment of passage in said valve whereby a greater diversity of operation is permittedV and controlled by a. single "valve, and to provide avalve ofthis kind which ips-compact in construction and simple in operation.

An illustrative vembodiment of this invention is shown in the accompanying drawings,vin which:

Figure 1 1s a front elevation of the improved valve, the dotted outlines represent-^ ing the steam generating and sterilizing compartments. Fig.f2 is an enlarged longitudinal sectional elevation of the valve taken on the line A-A of Fig. 1.l Fig. 3 is an enlarged fragmentary sectional plan of the valve taken on the lineB-B of Fig. 1 showing the arrangement of the passages when the valve is set Jfor connecting the steam generator with the sterilizing chamber.` Fig. 4 is a transverse section of the same'taken on the line C-C of Fig.l2. Fig. 5 is a view similar to Fig?) but showingthe positionj of the valve for closing ,all'communicationj through the di'lerentpassages. Fig.` 6 isp another view similar to Fig. 3, but showing the position of the valvel for permittingy communication between the sterilizing chamber and the dischargepassage of the valve. Fig. 7 is-a similar viewshowing the position of the valve when `set for creating avacuum in the' sterilizing chamber.

In the construction shownin the draw-V ings, the valve comprises a casing 1 and member or plug 2, the latter Vof which is of the usual tapered construction, and is rotatably held in a socket 3 by means of anut 4.

The nut 4 is threaded onto the casing 1 andhas an annulaniange 4.1 engaging van anp Specification of Letters Patent.

nular shoulder 5 onsaid member which sejcures the member against displacement. A handl wheel 6 or other operating device is secured to the member' for the purpose of rotatingthe same.

The casing 1: is adapted to be placed upon the front rim of -a sterilizer and to have pipes 7 and 8 connected thereto leading respectively to the steam generator chamber 9, represented bythe space .between the dotted circles Aand B (Fig. 1), and a sterilizing chamber 10, represented by the space within theL dotted circle f B.

A plurality of'passages are formed in the casing land member 2, so that for different angular positionsof said-member they kwill connecteither the steam generating 'chamber 9 with the sterilizing chamber 10',V orV the sterilizingv chamber 10 with the dis-y charge, or connect the steam generator 9 and the sterili'zing chamber 10 with an ejector for the purpose of Vexhausting, the sterilizer chamber to create a vvacuum therein. These passages lcomprise radially disposed passages 11 and 12 formed in the casingk 1, and connecting with the pipes 7 and 8 respectively,throughthe medium of cham-` bers 13 and 14 and passages 15 and 16.'

Y Y A radially disposed passage 17 is formedv in the member2 so as to coact with the passaves 11'and 12 in 'controllin commun-ication between the Vsteam generator andthe sterilizing chamber. Branch passages 18 and 19 are formed in the casing 1, connecting with the chambers 13and 14 by means of which they 'communicatedirectly with the by-passages 15'and 16. These branch passages `are arranged so `as tov coact with diagonal passages 20, 21, and 22 formed in the member 2fto permit the chambers 9 and 10 to beconnected in4 various ways with the axially disposed discharge passage 23. The .i

passage 2O`connectsy with an axially disposed passage 24 formed in the end of the member 2, which in turn communicates ,withr a passage 25y formed in the nozzle 26 secured to p the end of the member 2 in alinement with the discharge passage 23. The passages 21 and 22 are formed Vsonas to open into the chamber 27k formed between the end of the member 2 andthe casing 1.v The angularty ras of the passages 20, 21, and 22 is arranged so that the passage 21 Will reglster With the branch casing passage 1.9. for a. certainkposition of said member, and the-.passagesft 20y and 22 Will register simultaneously With the branch 'casing passages k18 and 19 respectively for anotherfpositionv ofthe mem-t ber 2. The discharge passage 23'isYformed-" ina nipple 23 Which is screwed into the end of the casing 1 and locked 'by means' of' a nut ,29, sothat the end of the nozzle 26 pro` jects slightly into they innerend ofthe passage 23, thereby forming an ejector coni-fi struction. The outer end of thek passage 23 diverges somewhat in. the-formloff a nozzle.`

A pointer 30 is secured to the member'2'j so as tocoact Withumarkings on a` dialg31- Vsecured' to thecasing l for indicating the various positions of the valve;V Asshown in Fig. 1 there arel four f positions, the markings therefor beingl respectively. Steril, .Closed-, Exh and. VacuumfY Pinsv or shoulders'32 are formed. onE thedial 31, in position tof'bexen'gaged by' theA pin 30 for limiting the'rthrovv of the member12. When the valve isturned so that:4

so that through the mediumL of the-chamberr 14 and passage 16 the sterilizing cliamberfr 10 communicates directly with i the discharge passage 23, and permits the steam.

exhaust through said .discharge passager.

` When the valvehas been shifted' sof-thatthe1l pointer 30 registersf-Withthe' last f of theabove named dial markings,- the. diagonal ing chamber 10, so as to produce a vpartial vacuum therein.

rllhisarrangement of the` valve provides a very@ compact device- Whiclr is extremely simple in its operation, and so arranged that there is little, if any, danger of faulty opera-tionl ofrj the ster-ilizer.
